My Woods BW12 is setup for a single remote. It's actually only a single line going back to the mower (power up, gravity down, so no need for 2 lines). When I got it, I thought I'd replumb it for 2 or 3 remotes, my tractor has 3 remotes on it, so I figured "why not". Well, 3 years later, it's still setup for a single. It works great, it's easy to hook up with a single hose, and I really have no need to raise the wings independently. As others have said, you have to shut down the PTO to lift the wings, the only CV joint is on the PTO shaft, so if you lift while it's running, you're gonna stress the heck out of the shaft/break it.
Anyway, yes, you can run it on a single remote and, honestly, despite having plenty of remotes, if I bought another one tomorrow, I'd have it setup for a single again. The ease of hookup and lack of hoses is very nice.
I have a rear blade with 3 cylinders on it (tilt/angle/offset) and I dread hooking that thing up. 6 monster hoses, and you have to get them "right" (one to input, one to output). Sounds easy, in practice, it's a PITA. For that thing, I do need all the remotes, but, if I could do with fewer, I would.
